METAL-BREAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 569,793, dated October 20, 1896. Application filed June Z9, 1896. Serial No. 597AG4. (No model.)

To all whom it 11mg conce/'1a.'

Be it known that We, CHARLES L. MILLER and JEROME R.Gnonen,citize11s of the United States, residing at Chicago, Cook county, Illinois, have invented certain new and useful Improvements in Metal-Breaking Machines, of which the followingis a specication.

This invention relates particularly to machines for breaking cast metal, and has for its object the providing of a simple, economical, and eicient metal-breaker; and the invention consists in the features, combinations, and details of construction hereinafter described and claimed.

In the accompanying drawings, Figure l is a plan vienT of a machine built in accordance with our improvements looking at it from the top Fig. 2, a transverse vertical sectional elevation, taken on line 2 of Fig. l, looking in the direction of the arrow; and Fig. 3, a front elevation, partly in section, taken on line 3 of Fig. 2, lookin g in the direction of the arrow.

In the art to which this invention relates it is customary in breaking metal which has been cast into long pieces to feed the piece into the machine in a step-bystep manner, and break it one piece at a time every time the metal is fed forward until the entire piece is broken or disposed of. This is necessarily an expensive and cumbersome Way of doing the work in that it takes a long time to break a long piece into eight or ten slabs or smaller pieces, While at the same time requirin g mechanism or an operator to stand at the machine the whole time in order to feed the piece forward.

The principal object of ourinvention therefore is to remove these two objections and provide a machine that Will break the long piece into the desired number of smaller pieces at one rotation of the operating-shaft, but which at the same time Will merely cut one at a time, as hereinafter described.

In constructing our preferred form of n1achine in accordance Wit-h our improvements We make a frame or base portion A of the desired size, shape, and strength necessary to contain and support the operative machinery. This frame or base portion is arranged on a suitable foundation B, formed principally of masonry, which will raise the machine to such a height that railway-tracks C may be laid adjacent thereto, upon which a gondola or iat carD may be run adjacent to the machine, so as to receive the broken metal, as hereinafter described. With a series or set of supporting anvil portions E, arranged to hold the piece of metal e in position to be operated upon. In order to guide the piece quickly and efiiciently to the position to be operated on, we prefer to provide fingers e', curved in the right direction, so that all the operator has to do is to practic-ally bring the metal to a correct position longitudinally with the machine and drop it on these fingers, which guide it rapidly to place. The pieces may be fed into the machine by manual labor or by the use of cranes or similar mechanism.

In order to break the metal into the desired number of pieces at one rotation of the shaft, We provide whatwe term a rotating breaking-shaft G, and provide it wi th a set of breakng'leve arms 9' y', g2, g3 Q4 Q5 Us, md Q7, that are arranged in different longitudinal planes with relation to the longitudinal center of the shaft, so that during the rota-tion of the operatin g-shaft the breaking-arm g will first contact the metal, as shown in Fig. 2 of the drawings, and break off that portion entending out from the face of the anvils E. The remaining breakingarms will then act successively, so that but one piece is broken at a time; but durin g the rotation of the shaft the entire piece is broken into the desired number ot' smaller pieces. By this arrangement it will be seen that the breaking-shaft has onlybeen subjected to the strain incident to the breaking of one piece. Further, it will be noticed that no feeding forward is necessary. All that is required is for the operator to lay the metal slab on the anvil, which is done both economically and efficiently by the aid of the fingers, the breaking-arms operating successively to break it into the desired number of smaller pieces at one rotation of the shaft.

The frame portion of the machine is provided at a with an inclined portion that receives the broken pieces and discharges them to the front of the machine and onto a car or vehicle, on which it may be transported to npoint of shipment or storage. This inclined portion has an extending swinging apron por- This framework is provided IOO tion a, that is pivoted at d?, so that it may be swung` up or down out of the Way to allow a box-car or engine to passy by the same.

In order to operate the machine and transmit power from a suitable source, ive provide i a train of compound gearing, comprising suitable gears H h lt and pinions 71.2 h3, together with the driving-pulley H. This compound gearing is for the purpose of reducing the speed and increasing the power; and We do not desire to be limited to this particular form, but to adopt any Well-known or modified form of gearing which'the particular conditions or circumstances may require.

Vhile We have described our invention in one specific structure with more orless minuteness. as regards details and as being embodied in certain precise forms, We do not desire to be limited thereto unduly any more than is pointed out in the claims. On the contrai y, We contemplate all proper changes in form, construction, and arrangement, the omission of im material parts and the substitution of equivalents, as circumstances may suggest or render expedient.

We claim- '1. In a metal-breaker, the combination of a supporting portion for the metal piece or bar. and a rot-ating shaft provided with a plurality of breaking-lever arms arranged to strike the metal bar and break it into a plurality of smaller pieces during one rotation of the shaft, substantially as described.

2. In a metal-breaker, the combination of a supporting portion for the metal, a rotating shaft, and a plurality of breaking portions arranged to be operated by the shaft to act successively and break up a bar one piece at a time, substantially as described.

3. In a metal-breaker, the combination or' a plurality of supporting portions or anvils, a rotating shaft, and a plurality ot' breaking lever arms arranged to be actuated thereby and so as to contact the metal bar successively and break it into a desired number of pieces during one rotation of the shaft, substantially as described.

4t. In a metahbreaker, the combination or' a supporting portion for the metal, a rotating shaft provided with a plurality of breakinglever arms arranged thereon so as to strike the metal bar successively and break it into a desired number of pieces during one rotation of the shaft, and means for guiding the vmetal bar into the desired position, substantially as described.
